While completing an admission assessment, the nurse is unable to palpate the client's left dorsalis pedis (DP) pulse. Which intervention is most important for the nurse to implement?

A. Use a Doppler to assess an audible DP pulse. This is the most immediate and effective intervention to locate a pulse that is not palpable. A Doppler device can detect blood flow that is not perceptible by palpation. B. Assess capillary refill distal to the DP pulse. While assessing capillary refill can provide information about peripheral circulation, it does not help locate the pulse. C. Review client's history for vascular disease. This is important for understanding the client's overall health, but it is not an immediate intervention to locate the pulse. D. Place a mark where DP pulse is auscultated. Marking the pulse location can be helpful once the pulse is found, but it is not an intervention to find an initially absent pulse.
